Ancient Thunder keno is a standard 80 spot keno game with a 20 spot draw, and 15 bonus spots. The player may select between 2 and 10 spots. 15 Bonus Spots are randomly selected. Hitting a bonus spot will show a matching hit on the bonus legend on the left of the keno grid. When a bonus spot legend is filled with hits, the bonus for that character will be triggered. Hitting the bonus multiplier coin does not fill any bonus legend spots.
